Network performance on the Einstein radius under the assumption of a lowest Einstein radius θ_E, min of 0.5″ and a weighting factor of w_θE = 5. Left panel: histograms of the ground truth (tr) in red and of the predicted values in blue. Right panel: direct comparison of the predicted against the true value, where the red line indicates the median of the distribution and the gray bands give the 1σ (16th to 84th percentile) and 2σ (2.5th to 97.5th percentile) ranges. From top to bottom: are the five different model parameters, lens center x and y, complex ellipticity e_x and e_y, and Einstein radius θ_E. For all plots 30 bins over the plotting range are used.
